Product Overview: The NA 4900 Needle Roller Bearing
The NA 4900 is a high-precision machined ring needle roller bearing with dimensions of 10x22x13mm. As a key component in our NA Series, this bearing is designed for applications demanding high radial load capacity within a very compact space. It features a machined and ground outer ring with flanges, a needle roller and cage assembly, and a removable inner ring. This construction makes the NA 4900 suitable for use on shafts that have not been hardened and ground, offering greater application flexibility. Part of our extensive range of Needle Roller Bearings, this component provides a reliable and space-saving solution for a wide variety of industrial and automotive machinery.
Key Features of the NA 4900 Bearing
- High Radial Load Capacity: Engineered with a full complement of needle rollers to support heavy radial loads.
- Compact and Rigid Design: The low cross-sectional height saves space, while the rigid machined outer ring prevents deformation under load.
- Includes Inner Ring: Comes complete with a separable inner ring, allowing it to be used on shafts that are not hardened.
- Precision Engineering: Manufactured to tight tolerances for smooth, efficient, and reliable operation at high speeds.
- Flanged Outer Ring: The outer ring flanges guide the needle rollers, ensuring stability and optimal performance.
- Versatile Mounting: The separable inner ring simplifies the mounting process and allows for different configurations.
